The outdoor comfort is affected by a lot of factors, i.e. wind velocity, solar radiation, convective and radiative heat transports, etc. RecentIy, there have been some attempts to develop the numerical method for predicting the human comfort incorporating the effect of these factors. This paper presents the results of numerical study on effects of cold surface due to snow on radiation and convection fields aroud buildings. In this study, radiative and convective heat transports near the model of building blocks are analyzed by CFD (Computational Fluid Dynamics) and radiation computation using meteorological data of Niigata City on Feburaly 3. Next, spatial distribution of SET* (Standard Effective Temperature) is calculated in order to assess the pedestrian level comfort using the data given from the CFD prediction.
